Abstract

The buffer circuit includes pull up and pull down circuits configured to selectively pull up and pull down, respectively, a voltage of an put/output pad. The pull up and pull down circuits are connected to separate power supply lines such that a current path from the input/output pad to the pull down circuit through the pull up circuit does not exist when electrostatic discharge is received at the input/output pad.
